Abstract

Provided is an image processing apparatus according to which it is possible to correctly determine a state of halation that has occurred in an eye. The image processing apparatus corrects at least part of a face image, and includes: an image acquisition unit configured to acquire an input image; a region extraction unit configured to extract a pupil region, which is a region corresponding to an eye of a person, from the input image; a pixel extraction unit configured to, in the pupil region, extract a pixel whose brightness is higher than a threshold value; a determination unit configured to, based on the result of extraction performed by the pixel extraction unit, determine whether or not halation has occurred in the pupil region; and a correction unit configured to, based on the result of determination performed by the determination unit, perform processing for correcting halation on the pupil region, wherein the pixel extraction unit sets the threshold value based on a bias of a brightness distribution of the pixels included in the pupil region.
